Specification of Letters Patent.

Patented Apr. 14, 1914.

Application filed December 30, 1912. Serial No. 739,287.

To all whom, it may concern Be it known that I, SAVIL D. MERCER, citizen of the United States, residing at Eldorado, in the county of Jackson and State of Oklahoma, have invented new and useful Improvements in Operating Means for Ohurns and other Devices, of which the following is a specification,

My present invention relates .to means for operating churns and other devices, and consists in the peculiar and advantageous construction hereinafter described and claimed.

In the accompanying drawings,which are hereby made a part hereof: Figure 1 is a view, partly in elevation and partly in verti cal section, of my novel means in connection with a churn. Fig. 2 is a section on the line 22 of Fig. 1. Figs. 3 and 4 are sections taken on the lines 3-3 and .2-4, respectively, of Fig. 1. Fig. 5 is a fragmentary elevation showing the collar on the dasher rod. Fig. 6 is an enlarged section showing the bearings of the two shafts. Fig. 7 is a detail section taken on line 77 of Fig. 6. Fig, 8 is a detail section taken on line 8-8 of Fig. 7. Fig. 9is an enlarged detail section showing the inner bearing of the crank shaft.

Similar numerals designate corresponding parts in all of the views of the drawings, referring to which:

1 is a base, which is preferably of hard wood. On the said base is fixed at certain points a resilient band 2, which is designed to be clasped by a bolt 3 and nut 4. about the churn body 5, so as to hold said body against casual movement on the base while the churn is in operation, and yet permit of the body being removed when it is desired to discharge it of its contents, and also when it is necessary to clean it. The said base 1 is also provided with a metallic casting 6 suitably fixed thereon. In said casting 6, and also in the base are formed vertical apertures; the aperture 7 of the casting being registered with the aperture 8 of the base, and the aperture 9 of the casting being registered with the aperture 10 of the base. Threaded through or otherwise secured in the aperture 7 and extending down into the aperture 8 is the comparatively large support 11 of the working parts of the churn, and threaded through or otherwisesecured in the aperture 9 and extending into the aperture 10 is the comparatively small support 12 which carries the crank shaft, hereinafter described. The support 11 is formed of gas plpe sections connected by unions 13, Figs. 1 and 6, and its lower section is fixedly connected with the support 12 through the medium of an interposed brace 14, Fig. 1. Said support 11 is provided with an overhanging arm 15, and said arm 15 is provided with vertically disposed apertures 16, Fig. 3, for the play of the dasher rod 17, and is equipped with anti-friction rollers 18 to prevent wear of the dasher rod 17. Arranged in the intermediate section of the support 11 is a circular series of anti-friction rollers 19, Figs. 6 and 7 and also arranged in said intermediate section is a circular series of anti-friction rollers 20. J ournaled within the group of rollers 19 and extending through the intermediate support section is a horizontal shaft 21, equipped with a spur gear 22 and a combined balance and hand wheel 23. In the group of rollers is journaled a shaft 24 which extends through the support section at diametrically opposite points and carries a comparatively small spur gear 25 which is intermeshed with the gear 22. p

p The support 12 is also formed of gas pipe, and has an overhanging arm 26 in which is arranged a cage 27 carrying a circular series of anti-friction rollers 28. Said overhanging arm 26 is provided with a tubular extension 29, Fig. 1, which is registered with the space within the rollers 28, and the shaft 2 1 extends through said extension 29 and said space within the rollers 28. The crank 30 of the shaft 2 1 is pivotally connected with a pitman 31, and said pitman is pivotally or loosely retained on the lateral rod 32 of the collar 33. This collar 33 comprises a section 341 having a pin 35, a section 36 hinged at 37 to the section 3 1 and carrying a set screw 38, and a fastener 39 pivoted on section 36 and notched to engagethe pin 35. The collar 33 is fixed by the set screw 38 on the dasher rod 17, so as to assure the dasher rod moving with the pitman 31 when motion is transmitted to the latter, and by reason of the construction best shown in Figs. 1 and 5, the collar can be readily released from the dasher rod when it is desired to raise the dasher rod and the dasher body 10 to a point above and clear of the churn body 5. It will also be understood that after the removal of the churn body 5, the dasher body and the dasher rod may be expeditiously and easily separated from the other parts and hence said dasher body and rod can be conveniently and thoroughly cleaned.

It will be gathered from the foregoing that with the elements arranged as shown in Fig. 1, the cover 41 of the churn body can be readily raised on the dasher rod 17, and the cream can then be conveniently poured into the body. Then after the cover is replaced on the body 5, the operator actuates the wheel 23, when, as will be manifest, the dasher rod and dasher body will be rapidly V and powerfully reciprocated, and this with but little effort. It will also be gathered that my novel operating means is at once inexpensive and durable, and is well adapted to withstand, without impairment, the rough usage to which churn-operating devices are ordinarily subjected, as well as exposure to the weather. This latter is due in large measure to the employment of the hollow supports, and the housing of the antifritcion bearings in the said hollow supports, whereby the said bearings are covered andprotecte Having described my invention, what I claim and desire to secure by Letters-Patent, is

The herein described operating means, comprising a base, a support formed of gas pipe and having an upright portion and an overhanging arm; said support being fixed at its lower end to the base, a comparatively small support formed of gas pipe and fixed at its lower end to the base and having an overhanging arm disposed belowand in the same vertical plane as the firstnamed overhanging arm, means fixedly connected to and fixing said supports with respect to each other, upper and lower horizontally disposed anti friction bearings housed in the upright portion of the comparatively large support, horizontally-disposed anti-friction rollers housed in the overhanging arm of the large support and spaced apart adjacent the upper end thereof, a shaft journaled in the upper of the horizontal hearings in the upright portion of the large support, a spur gear fast on said shaft, means for transmitting rotary motion to said shaft, a horizontally-disposed antifriction bearing housed in the overhanging arm of the comparatively small support, a crank shaft journaled in said bearing and also in the lowermost horizontalbearing in the upright portion of the comparatively large support, a spur gear fast on said shaft and intermeshed with the first-named spur gear, and a dasherrod means for'connecting the said crank shaft withthe dasher rod.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
